Question

sierra has a total of 61 dimes and quarters in her piggybank. she has 3 more quarters than dimes. the coins have a total value of $10.90. how many dimes and quarters does she have

Answer 1

Lets convert the dimes and quarters to dollars.

1 dime = 0.1 dollar

1 quarter = 0.25 dollar

Now let the dimes be x

The quarters will be x + 3

So :

x + x + 3 = 61

2x + 3 = 61

2x = 61 - 3

2x = 58

x = 29

So we have 29 dimes

Quarters = 32

She has 29 dimes and 32 quarters
